Heat bearing cone (20) to a maximum temperature of 135 °C (275 °F).
Install bearing cone (20) on the axle shaft so that there is slight end play. Apply clean SAE 30 oil to the bearing cone, when the bearing cone (20) is cool.Note: The adjusting nut must be installed so that the part number is facing away from bearing cone (20) .
Apply clean SAE 30 oil on bearing nut (12) . Install bearing nut (12) on the axle shaft. Tighten the nut until a small amount of end play remains.Note: The seal drag torque is the torque that is needed to rotate the axle housing.

To measure the seal drag torque, install Tooling (G) on the axle housing. Place a torque wrench on the bolt at the center of the bar, as shown. Use the torque wrench to rotate the housing. Record the reading on the torque wrench.

Rotate the axle housing. Use Tooling (D) to tighten bearing nut (11) . Install Tooling (G) on the axle housing. Place a torque wrench on the bolt at the center of Tooling (G) . The torque wrench reading is equal to the seal drag torque plus the axle bearing preload rolling torque. Use the seal drag torque that was recorded in Step 19.Note: The preload rolling torque for new bearings is 4 N m (3 lb ft) to 9 N m (6 lb ft). The preload rolling torque for used bearings is 4.5 N m (3 lb ft) to 3 N m (2 lb ft).
Make sure that axle shaft (6) has zero end play.
If the axle bearing preload rolling torque exceeds the specification, back off nut (11) by 1/8 turn and reseat bearing cone (20) against nut (11) . Perform Step 19 again.

The following steps are for the assembly of planetary carrier assembly (5) :
Install retaining ring (3) in the carrier.
Apply a thin coat of clean SAE 30 oil in parts of planetary carrier assembly (5) .
Install bearing (9) in planetary gear (10) .
Install thrust washers (11) and planetary gear (10) in the carrier.
Install shaft (6) in the carrier. Make sure that the spring pin hole in the shaft is aligned with the spring pin hole in the carrier. Install new spring pin (6) through the carrier and in shaft (7) . Install spring pin (6) slightly below the outside surface of the carrier.
Repeat Step 23.a through Step 23.e for the remaining two planetary gears.

Install Tooling (C) and suitable lifting slings to planetary carrier assembly (5) .
Use a hoist to install the planetary carrier assembly (5) in the axle housing assembly. The weight of the planetary carrier assembly is 80 kg (176 lb).

Use Tooling (F) to install retaining ring (3) on axle shaft (6) .
Remove axle housing assembly (2) from Tooling (F) . Install the bottom half
